VE AND BURNER.

SPECIFICATION forming part of Letters Patent No. 596,086, dated December 28, 1897.

Application filed July 18,1896. Serial llo. 599,750. (No model.)

To aZZ whom it may concern.-

Be it known that I, CARL ERNST OSTLUND, a subject of the King of Sweden and Norway, residing at Stockholm, Sweden,have invented certain new and useful Improvements in Petroleum-Stoves and Burners for Gas Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanymarked thereon, which form a part of this specification.

My invention relates to improvements in wickless petroleum-lamp stoves in which the petroleum is forced up into the burner from the tank either by the force of gravity or by means of compressed air.

The object of the invention is to provide a stove of this character in which a more complete combustion of gas takes place, thereby giving the flame more effect over the burners of this class of stoves heretofore in use.

In a detailed description of the invention reference is made to the accompanying drawings, of which Figure 1 is a vertical projection, partly in section, of apetroleum-lamp stove fitted with my improvements; Fig. 2, a reduced longitudinal section on line 1 1, Fig. 3 Fig. 3, an enlarged plan of the burner; Fig. 4, a transverse section on line 2 2, Fig. 2; Fig. 5, a plan seen from two different sides of the blank from which the burner is made.

The burner is tightly fitted on a tube that rises from the tank A and consists partly'of a upper ring-shaped flanged portion 0, on which a disk or plate 6 is placed; To the upper part ofthe said tube there is fixed a mouthpiece or nipple 'i with a minute opening '6, as is usual in petroleum-lamp stoves.

An important part of the invention consists in the formof the burner part b. This make this burner part as follows: A piece of sheet metal j is bent into the shape shown in the side view to the right of Fig. 5, after which the cuts are made in the bent-out part of the sheet metal, which is then bent round a cylindrical mandrel, and thus given the above-described form, and finally the ends of the aforesaid metal plate thus bent into a cylindrical form are soldered together. In bending the blank shown in Fig. 5 the openings between the lamellze are formed antomatically, which is the main advantage of this method of making the burner part b. The part b is made fast to the upper ringshaped part c. The disk or plate 6 can be laid loosely or otherwise placed over the part o. By means of this form of burner the air is heated before the combustion of gas takes place. The pipe leading from the tank, it

will be observed, has the jet or flame orificev directly in its upper end and practically forms a portion of the burner.

The air-pump for forcing air into the tank A is located in said tank and is shown in longitudinal section in Fig. 1. The pump-cylinder consists of a tube f, one end of which is inserted and tightly fastened at one end in the usual manner into the wall of the tank and which extends over to the opposite side of the tank, where its other end is passed into a collar 9, that is tightlyfastened to that side of the tank-wall. At this end the tube is provided witha bottom in which there is a valve-opening to, which is shut by a valvebody h, loosely placed inside the collar g. This valve-body is pressed against the valveseat by a spiral spring is, supported by the screwed-down lid 11 of the collar g. The piston Z of the pump is in this case not provided with any valve for admitting air into the pump-cylinder; but for this purpose the pump-shaft Z is instead formed of a tube on whose exterior end there is fastened a perforated button n, by means of which the room behind the piston-rod is brought into communication with the outer air as soon as the thumb of the operator is removed from the opening in said button n, which takes place every time the piston-rod is pressed in. The arrangement of the collar 9 is intended to facilitate getting at and repairing or cleaning the valve of the air-pump by screwing oflt' the cap 2'. The tube f may not, of course, be fitted tight into the collar g, in order that the air may freely pass from the valve to the interior of the tank.

In making the burner according to the method illustrated in Fig. 5 the plate or blank may of course be bent out into any desired shape-for instance, as illustrated by the dotted lines in said Fig. 5. A cup 0 for heating the burner preparatory to lighting is placed above the oil-tank, which thus does not become so heated that the oil will rise high enough to escape through the opening in the burner, but only warm enough to make the oil rise a little way in the tube supporting, the burner until the oil is gasified and the gas lighted by the flame in the cup 0.

Having fully described my invention, I claim 1. A burner for petroleum lamps or stoves, formed of a plate or blank having a bulged or outwardlyprojecting portion in which there are a series of incisions, the said plate or blank being bent into tubular form, and its edges united, substantially as shown and described.

2. I11 a petroleum-oil stove, the combination with a tank, and a tube or oil-pipe extending therefrom, having a nipple or jet in its upper end; of a burner forming a continuation of said tube or oil-pipe, and consisting of a bent plate or blank having a bulged or outwardly-projecting annular portion in which there are a series of incisions, the said plate or blank having its edges united as herein shown and described.

In testimony whereof I affix my signature in presence of two witnesses.

CARL ERNST OSTLUND.
